Johnson 223 Resto, part 2...

 This is the 2nd phase of this restoration... I picked this old Johnson CB Base station up at a local yard sale. It looked like it was at the end of its road. I have a soft spot for these old rigs, so decided to give it a face-lift. It needed all of the typical stuff....caps, a handful of resistors, switches & controls needed service, tube sockets and pins cleaned, and few crystals that had drifted out of spec, a knob bright, the mic needed a major cleanup, and she got a full alignment. Here's a few pics and vids...





This was one of the donor radios I used for crystals and knob brights...


I also salvaged the channel selector to replace this mess...


These crystals are almost unobtainium, these days...


More donor radios in the shop floor :-)  

Chassis cleaned...I'm pointing where the rectifier tube once was. It now has a solid state rectifier...

Slowly coming together...

Filter cap replaced under the chassis, the old can-type cap is still up top for looks :-)

Various other caps replaced...

Installing new feet on the cabinet...


Pop riveted from the inside...


 Tuned up, nice and clean tx audio!
